STOP AND WASTE COCK.

SPECIFICATION forming part of Letters Patent No. 586,710, dated July 20, 1897. Application filed July 3, 1895. Renewed May 19, 1897. Serial No. 637,307. (No model.)

To a, 'll'7L-07lb it may concern.-

Be it known that I, Josnrn H. L ons, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Stop and aste (Jocks,of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in combined stop and waste cocks; and the objects of the invention are to provide a form of cock which shall be reversible from left to right and in which the stop is concealed from View and protected from the danger of clogging or injury likely to occur in exposed forms of stops.

A further object of the invention is to pro vide an independent stop which can be entirely removed from the barrel of the cock, thus transformingit into a steam or gas cock for general use.

My invention consists in the recessed bottom of the barrel and concealed stop therein, with the detail construction of the stem-extremity and fastening device therefor, as hereinafter described, shown in the accompanying drawings, and more specifically pointed out in the claim.

In the accompanying drawings, Figure 1 is a vertical central section through the open cock. Fig. 2 is a bot-tom View with outside washer and not removed. Fig. 3 shows the extremity of the stem, washer, nut, and reversible stop-plate separated in detail.

In the figures, 1 is the cock-barrel. 2 is the opening therein. 3 is the stem. 4 is the water-passage registering with the opening in the barrel. 5 is a recess in the bottom of the barrel, about the extremity of the stem, in which rests the plate 6, cut away at 7 to permit the free lateral movement of the key or extension 8 upon the reduced extremity 9 of.

the stem within the angle of its arms 10.

A lug 11 on the stop-plate is inserted in the recess 12 in the ring of the bottom of the barrel to prevent the plate from turning. After the plate has been inserted the Washer 13 is placed over it and the fastening completed by the nut 14. This washer turns with the stem, since the extension 8 of the stem passes through a keyway 15 therein.

It will be seen that the stop-plate may b cut to stop at one-quarter turn for Waste-outlet or at one-half turn for certain uses, as for gas, for safety, to insure entire closure of the cock. These changes can be easily made by cutting the lateral extensions on the plate to limit or extend the movement of the stem.

The plate can be reversed in position by turning it over and so making the cock rightor left at pleasure.

The stop is entirely independent of the other portions of the device and when removed the stem will turn freely around Without stopping and the cock will be transformed into a common gas or steam cock.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-- In a reversible stop and Waste cook, the combination of a cock-barrel, recessed at the outer extremity at 5 and provided with a transverse recess 12 in the Wall of the recess 5, with a stop-plate 6 resting in said recess 5 and cut away to present arms 10, and provided with lateral lug 11 adapt-ed to enter said recess 12 in the cock-barrel, a central stem 3 provided with a threaded extremity upon which are placed a clamping -nut 14 and washer 13, and a lateral extension 8 adapted to engage alternately the arms upon said stop-plate, and passing longitudinally into the keyWay 15 in said Washer whereby the washer will turn with the stem, substantially as described.

In testimony whereof I hereunto set my hand this 24th day of June, 1895.

JOSEPH II. LYONS.
